In this problem, we are required to apply conservation of energy. We'll need the conservation of energy equation.
Law of conservation of energy:
, where Wnc is the work done by non-conservative forces such as friction.
A car is parked at the top of a 52m-high hill. It slips out of gear and rolls down the hill. How fast will it be going at the bottom? (Ignore friction.)
